As life expectancy continues to rise, so too does the likelihood of developing chronic conditions such as diabetes and heart disease. While this presents significant healthcare challenges, advances in medical technology such as minimally invasive surgical techniques are helping people live healthier, longer lives. These innovations have fueled growing demand for medical equipment and specialized surgical tools. At the same time, the industry faces new pressures. A recent report by GlobalData[1] highlights how rising material costs and component shortages in recent years have disrupted the medical device market. As a result, many healthcare providers are reassessing their supplier relationships to ensure reliability, cost-effectiveness, and continued access to essential tools.

The CWT Advantage: Exploring Value-Added Services that Power Medical Innovation
Cleanrooms & Cleanroom Assembly
CWT’s cleanrooms provide end-to-end solutions for medical device manufacturing, assembly, and packaging. By maintaining strict cleanliness standards, these facilities ensure that bioburden-sensitive components and sub-assemblies meet the highest quality requirements. OEMs, designers, and researchers can rely on certified cleanroom packaging and assembly processes to deliver precision, consistency, and compliance for even the most demanding medical applications.
Laser & Plasma Welding
CWT’s laser and plasma welding services are designed to join ultra-fine wire components with exceptional precision, particularly small-diameter medical wire. By integrating this process into device manufacturing, OEMs can significantly reduce lead times and avoid supply chain challenges often associated with complex assemblies. Typical applications include stents, hypotubes, guidewires, ball tips, sensors, cannulas, and needles, making welding a critical step in advancing medical device performance and reliability.
Laser Marking
CWT’s laser marking services provide precise, permanent identifiers on a wide range of medical components. In addition to serial numbers, part IDs, and other markings, depth bands can be applied to guidewires, K-wires, and pins, giving clinicians a clear visual reference for insertion depth. This process enhances usability, improves traceability, and supports regulatory compliance, all while maintaining the integrity of delicate medical devices.
Ink Pad Printing
CWT’s pad printing services provide high-quality, durable markings across a variety of medical devices. Using medical-grade black ink, this process is ideal for depth labeling orthopedic pins or applying product numbers to meet FDA tracking requirements. Common applications include catheters, tubing, K-wires, and a wide range of stainless steel and nitinol components. Pad printing ensures critical information is clearly visible, reliable, and compliant throughout a device’s lifecycle.
Passivation
CWT’s passivation process enhances the durability and safety of stainless steel components by applying a thin protective oxide layer that resists corrosion. During the process, free iron is removed from the surface, creating a passive chromium oxide film that strengthens and safeguards the metal. This service is commonly applied to guidewires, K-wires, core wires, coils, mandrels, Steinmann pins, and stylets, ensuring long-lasting performance in demanding medical environments.
Electropolishing
CWT’s electropolishing service uses an electrochemical process to smooth and brighten stainless steel surfaces by selectively removing microscopic high points. This results in a clean, uniform, and stress-free finish with improved corrosion resistance. The process is widely applied to guidewires, K-wires, core wires, coils, mandrels, Steinmann pins, and stylets. Components that not only perform reliably but also meet the highest standards for precision and biocompatibility.
PTFE (Teflon™) Coatings
CWT applies PTFE coatings to enhance the performance and versatility of medical components. Known for its non-stick properties, PTFE also offers high density, hydrophobicity, and resistance to extreme temperatures. Using spray or dip application methods, coatings can be customized in color, composition, and thickness to meet specific design and functional requirements. This adaptability makes PTFE an ideal choice for devices that require smooth operation, durability, and reliability in critical medical environments.
Simplifying Complexity: How Value-Added Services Streamline Medical Supply Chains
While CWT offers a full range of traditional manufacturing services, the company’s true strength lies in its ability to handle more complex medical devices.
“Often, customers aren’t aware of the exact processes needed to produce their products. CWT can help break down and identify the proper steps to manufacture the components successfully,” explains Jim Boldig, CWT director of sales and engineering. “Vertical integration is essential, so it is important to have as many services as possible in-house to be most efficient for the customer, who doesn’t like complex supply chains and long lead times.”
“We have custom assembly services in our ISO Class 7 cleanroom, and laser and plasma welding workstations join metal-based components; soldering and adhesive bonding stations join dissimilar materials,” notes Boldig. “Additionally, our ink-pad printing equipment, within our cleanroom, is available for sensitive projects. Printing is advantageous over other methods when the substrate is extremely thin or fragile. We also have printing equipment outside of the cleanroom to support rapid prototyping.”
CWT continues to expand its capabilities. Most recently, the company invested in a new 500 sq. ft. washroom, which features advanced ultrasonic cleaning systems and citric passivation processes. These additions strengthen CWT’s ability to deliver high-quality, fully integrated solutions, all while reducing lead times and simplifying complex supply chains for its customers.
In-House Laser Marking Services Deliver Efficiency and Value
One of CWT’s fastest-growing capabilities is laser marking. Introduced just five years ago as a limited-service department, it has since tripled in size to meet rising customer demand. Today, laser marking is heavily utilized by the grinding department for depth markers, part identifiers, part numbers, lot numbers, and UDI codes.
Depth markers, in particular, provide end users with anatomically correct location references, with the flexibility to customize size, font, logos, and even barcodes. While orthopedics remains the most common application for laser marking, Boldig says that CWT has also expanded its use to include cardiovascular and neurovascular guidewires.
In addition to its in-house services, CWT partners with trusted local and regional processors to provide electropolishing and PTFE coating. “These unique collaborations offer some of the best technical know-how in the medical device industry,” notes Jim Boldig. “Being within our geographic region, we can cut lead times and costs, reducing inefficiencies.”
